Re: [PATCH] Apply headset jack fixup for alc287 thinkpads

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Oops, turns out there's a non-bass variant of this quirk: ALC285_FIXUP_THINKPAD_NO_BASS_SPK_HEADSET_JACK
I've made a V2 of this patch using it - it's much less invasive.

I'm in agreement. If the quirk's name says it targets bass systems, then that'd imply a non-bass version is available, which should prevent future confusion.
